Last week I posted a short series on my blog about the need (or lack 
thereof) for nitrogen-fixing plants in small plots where the residents 
recycle their urine into the garden.  Based on Martin Crawford's figure of 
one pee (half a litre) containing about 5.6 grams of nitrogen, and using 
his numbers for nitrogen demand of different food forest canopy plants, I 
calculated that one person's annual urine should meet the nitrogen needs 
of 4100-5100 square feet of forest garden.

I also followed up with two other related posts.

Enjoy!
